Specification of Letters Patent.

Patented Aug. 29, i916.

Application filed January 5, 1916. Serial No. 70,400%-.

To all whom it may concern:

Be it known that I, JAMES S. BARTHOLO- MEW, a citizen of the UnitedStates, residing at Decoto, in the county of Alameda and State ofCalifornia, have invented certain new and useful Improvements inSwimming Apparatus; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to certain novel improvements in swimming apparatusand the object is to simplify and improve the construction and increasethe efliciency of manipulation.

To these ends the invention consists in the construction, combinationand arrangement of the several elements of the device as will behereinafter more fully described and particularly pointed out in theclaims.

In the accompanying drawing the same reference characters indicate thesame part of the invention.

Figure 1 is a perspective view of my improved swimming apparatus as itappears in the difi'erent strokes when adjusted to the human leg. Fig. 2shows the improved swimming apparatus in the water during the propellingfrog stroke and recovery stroke of the same. Fig. 3 is a similar viewshowing propelling and recovery of the scissors stroke.

On my drawing No. 9 is the flexible fabric havingits outer edge securedto a metallie or wooden or composition hoop restrained and stayed bycord or wire network and the flexible fabric is divided into strips ofapproximately even width to permit the water to flow easily through iton the recovery stroke but offering steady resistance on the propellingstroke of human or animal legs or on the demonstrating manikins andimages.

Figure 21 denotes a plurality ofhoops of metal, of wood, or ofcomposition, rigidly strung with a network restraining the flexiblefabric in a horizontal position about the human or animal legs by thegarters on the inside to the hoops on the outside.

Figure 22 denotes a secondary plurality of hoops secured to the insideof a flexible fabric of all hoops excepting the top hoop on the human oranimal legs and swinging clear of the legs. All parts are painted innational or collegiate or society colors.

Figure 23 denotes a network of cords or wires restraining a flexiblefabric 9 on all hoops.

The accompanying drawing shows my improvement in the best form now knownto me but many changes in the details might be made within the skill ofa good mechanic without departing from the spirit of my invention as setforth in the claims at the end of this specification.

Having thus fully described my invention what I claim and desire tosecure by Letters Patent is:

1. A swimming apparatus of the class described comprising a garter andinner or secondary hoop and a plurality of outer hoops, networksextending from the garter and from the secondary hoop to the outerhoops, a sectional flexible fabric restrained by each of said networks,the sections opening and closing under said network substantially as andfor the purpose set forth.

2. In a swimming apparatus of the class described a plurality of innerhoops and a plurality of outer hoops connected by a network restraininga flexible fabric.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JAMES S. BAR'IHOLOMEW.
